Calibration
Routine Checks
Gammex no longer offers certificates of conformance for scales – please seek out a local metrology
center for routine recertification if required. If adjustments are needed to dial in the scale, follow
instructions below for the calibration process.
Note:
Calibration might be required upon first use. This is especially true after an altitude change,
where gravitational force can vary for the same body of mass. Calibration of scales should be
checked over time as mechanical components are subject to wear.
Calibration Process
Required equipment:
•
10 kg certified weight or combination of certified weights.
Process
1
While the 163-DIG is off press and hold the
Unit
button while holding the
Power
button until the
display reads CAL. Immediately after, a random set of numbers appear (raw load cell value).
2
Press
Unit
again. The display now shows - - - - - - and then flashes the calibration weight to be
used (10 kg).
3
Place the 10 kg calibration weight on the 163-DIG platform.
4
When the stable indicator (
) is displayed, press the
Unit
button again and the display shows
- - - - - - followed by the new (raw load cell value).
5
Press the
Power
button to turn the scale off and then press
the Power
button. Calibration is now
complete.
